GE DS3800DFXD1B1B数字量输入卡件
Vb相量：显示Vb幅值和角度的相量表示。Vb使用Va角度作为参考点。如果PQM电压输入端没有电压，则Ia用作参考。当PQM配置为3线DELTA/2 VT、4线WYE/2 VT或单相直接连接时，Vb不显示。Vc相量：此处显示Vc幅值和角度的相量表示。Vc使用Va的角度作为参考点。如果PQM电压输入端没有电压，则Ia用作参考。当PQM配置为单相直接连接时，不显示Vc。Ia相：此处显示Ia幅值和角度的相量表示。Ia仅在PQM电压输入端不存在电压时用作所有其他相量角的参考，否则，Va用作参考。
Vb PHASOR: Displays a phasor representation for the magnitude and angle of Vb. Vb uses the angle of Va as a reference point. If there is no voltage at the PQM voltage inputs, Ia is used as the reference. Vb is not displayed when the PQM is configured for the 3 WIRE DELTA/2 VTs, 4 WIRE WYE/2 VTs, or SINGLE PHASE DIRECT connections. Vc PHASOR: A phasor representation for the magnitude and angle of Vc is displayed here. Vc uses the angle of Va as a reference point. If there is no voltage at the PQM voltage inputs, Ia is used as the reference. Vc is not displayed when the PQM is configured for SINGLE PHASE DIRECT connection.Ia PHASOR: A phasor representation for the magnitude and angle of Ia is displayed here. Ia is used as a reference for all other Phasor angles only when there is no voltage present at the PQM voltage inputs, otherwise, Va is used as the reference.
